摘要(Abstract)：

SARS-CoV-2(Severe acute respiratory syndrome coronavirus 2)，又称“新型冠状病毒”或“新冠病毒”，正不断进化和变异，产生了大量的病毒变异株（Variant），其致病性、宿主适应性和传播性变化显著，给COVID-19(Coronavirus disease-19)，又称“新型冠状病毒肺炎”或“新冠肺炎”的防治带来巨大挑战。变异株的命名对COVID-19的分子流行病学调查和防控技术研究起到关键性的辨识作用。本文综述了GISAID、Nextstrain、Pango、TILE和希腊字母5种SARS-CoV-2变异株的命名原则、适用范围和重要的流行变异株，为SARS-CoV-2变异株的监测、研究SARS-CoV-2变异株的进化机制、传播特性及抗原位点设计提供一定的参考。

关键词(KeyWords)： 新型冠状病毒;新型冠状病毒变异株;命名系统
